Columbia Blood Agar - Advanced Primary Isolation

Columbia Agar Base with 5% sheep blood utilizes specially selected peptones and beef heart infusion for optimal nutrition while maintaining superior hemolytic clarity. Enhanced formulation demonstrates improved pigment production, sharply defined hemolysis zones, and excellent colony morphology differentiation compared to standard blood agar.

Comprehensive Pathogen Recovery

First-line medium for respiratory specimens, wound infections, and blood culture backup. Definitive streptococcal grouping, fastidious Haemophilus recovery, and mixed flora analysis. Supports enhanced Staphylococcus pigment production essential for preliminary identification.
